Benign Liver Tumors

Benign liver tumors are relatively common. While most of them do not show any symptoms, some may cause hepatomegaly, right upper quarter disorder or intraperitoneal bleeding. Most liver tumors are detected by chance during the ultrasound or other screenings. Liver function tests usually give normal results. Diagnosis can usually be made with screening tests. Treatment is necessary only in a few specific cases.


Benign Liver Tumors 

The most common benign tumors in the liver are:
1. Hemangioma

2. Focal nodular hyperplasia
3. Hepatocellular adenoma



Hemangiomas are the most common of benign liver tumors. It is in the form of a mass which is composed of abnormal veins. It is more commonly seen in women.

These benign tumors usually do not cause any symptoms and do not need to be treated. In very rare cases, when a large hemangioma is seen in a baby, it may be necessary to be surgically removed in order to prevent clotting and heart failure.


Focal Nodular Hyperplasia

Focal nodular hyperplasia is the most common type of benign liver tumor after hemangiomas. They are mostly seen in women between the ages of 20-30. As in other benign liver tumors, they are often noticed in screening tests performed for another health problem. These tumors, which are also called as FNH, usually do not cause any symptoms and do not require treatment. If they are large, your doctor may recommend surgery, but it is a quite rare situation.


Focal Hepatocellular Adenoma

Hepatocellular adenomas are less common benign liver tumors. They are mostly seen in women who can have children. Since these tumors usually do not cause any symptoms, most can never be detected. In rare cases, these tumors break down and cause bleeding into the abdominal cavity. When doctors detect a large adenoma, they can recommend surgical removal of adenoma in order to prevent this risk. Hepatocellular adenomas may grow in women using hormone pills. Therefore, doctors often recommend these women to stop contraceptive pills and post-menopausal hormone replacement treatments.
